Circulator Pump Sizing
Sent: Thu Sep 29, 2011 3:08 pm
Hello, I am removing a wood boiler from inside my home and installing an AA260 coal boiler, which is in my garage about 70feet from the house. The lines from the garage to the house are 1inch H2o Pex 5 wrapped insulated tubing. This system is going run through the oil furnace in the home to the coal boiler in the garage. The home size is just under 5000 sq. ft. with base board.The insulated garage is 28x40 ft. with 12ft ceiling.
All lines coming off the coal boiler are 1 1/4 inch black iron going into the 1 inch pex tubing, feeding the oil furnace in the home.I was going to use a Taco 007, but I was advised that I should use a larger size pump, Preferably, a Taco 0013 or maybe a Taco 009 pump. The reason for using the larger pump, is the size of the 70+ feet of the 1 inch pex tubing.
My question is : What size circulator pump would you recommend using with the above facts?
